Interdisciplinary orthognathic treatment of high angle class III malocclusion

For Class III adult patients, combined treatment strategy must be followed which includes either further dentoalveolar compensation or orthognathic surgery following decompensation of the teeth. This case report presents the interdisciplinary approach of a skeletal Class III malocclusion with increased vertical facial dimension, occlusal cant, extracted posterior teeth on the right upper and left lower segments, extensive restorations, and total circular crossbite. The orthodontic alignment took 10 months. LeFort 1 osteotomy with 7 mm advancement, 5 mm impaction on the left side, 3 mm impaction on the right side and 2 mm rotation for midline correction toward the left side, 3 mm set.back of mandible with bilateral sagittal split osteotomy were done. The surgery simulation, postoperative and 2 year follow up records were compatible. The treatment was finalized in a straight profile with stable occlusion and good smile characteristics without airway disturbance.Key words: Interdisciplinary treatment, orthognathic surgery, skeletal Class II

Evaluation of corrosion resistance and surface characteristics of orthodontic wires immersed in different mouthwashes

PubMedID: 27886000Background: Patients use mouthwashes in addition to mechanical cleaning during orthodontic treatment. The effects of mouthwashes on the archwires have not been examined yet. Objective: To compare the corrosion resistance of four different arch wires and corrosion effects of different mouthwashes to formulate a biocompatible and mechanically useful arch wire and mouthwash combination. Methods: Each group comprised of 4 wire samples of 2 cm 0.016 × 0.022 inch. 1st group: ion implanted nickel titanium (INT), 2nd group: nickel titanium, without ion implantation (NT), 3rd group: micro layered esthetic nickel titanium (ENT), 4th group: stainless steel (SS) wires. They were immersed inside 2 ml of artificial saliva solutions (AS) for the control, or AS (9%) combined with 1 of the 3 mouthwashes (91%) for study groups, for 24 hours. These mouthwashes were essential oil (EO), chlorhexidine (CHX), sodium-fluoride (NaF). An electrochemical analyzer was used for electrochemical impedance spectroscopy measurements. Results: High corrosion resistance was obtained for ENT than the other wires. The corrosion potentials are 0.007, -0.042, 0.074 and -0.015 V (Ag/AgCl) for ENT, INT, SS and NT in the artificial salivary, respectively. In NaF containing mouthwash Rp value of ENT is significantly high in comparison to others. The impedance responses of all materials increased significantly in the presence of NaF mouthwash as well as in the CHX mouthwash. Low frequencies are seen at all materials in EO mouthwash. Diameters of loops are 22, 5.9, 5.9 and 3.7 M? at ENT, INT, SS and NT. Conclusions: In this study, micro layered esthetic nickel titanium wires are found biocompatible among other wires and NaF and CHX mouthwashes can be recommend for their good corrosion resistance during fixed orthodontic therapy. © 2016 - IOS Press and the authors.

Prospective analysis of nosocomial infections in a Burn Care Unit, Turkey

Background & objectives: Prevention of infection in burned patients poses a great challenge as infection is the most common cause of mortality after burn injury. An analysis of burned patients, admitted and treated between January 2004 and December 2005 in a nine-bed burn unit in Turkey, was performed prospectively to identify the common pathogens and incidence of nosocomial infection in these patients

Clusters of Poly(acrylates) and Silver Nanoparticles: Structure and Applications forAntimicrobial Fabrics

Silver−poly(acrylate) clusters have been synthesized in water by reduction of AgNO3 in the presence of poly(acrylates) of different molecular weights through two different methods, NaBH4 reduction and UV exposure. The structure of the clusters and the effect of the synthesis parameters on the size and polydispersity of the particles were evaluated by means of small-angle X-ray scattering (SAXS) and confirmed by UV−visible absorption and transmission electron microscopy (TEM). The results clearly show that the reduction method and the polymer chain length play key roles in the achievement of few-nanometer-sized nanoparticles. The effect of the pH was also investigated. The nanoparticle dispersions were then used to functionalize cotton, wool, and polyester samples in order to obtain antimicrobial textiles for biomedical applications. The antimicrobial activity of the as-treated samples has been tested against Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa, and Candida albicans
